I predict in the future there will be a taxless dollar store it will put all the other stores out of business do you think this is possible?

It would mean prison for tax evasion.

First tell me how you can buy a radio or computer accessories for a buck or two that was made in China and shipped to the US and then distributed to Dollar Stores?

I believe that in the future capitalism will be abolished and workers will receive vouchers to buy things. Eventually there will be no currency at all once communism fully takes over. Amazon will most likely be nationalized.

In San Francisco, there's an alternative cashless currency that's very popular.

It's called fellatio.
